The United States’ Perils of Presidentialism

In his seminal 1990 article “The Perils of Presidentialism,” political scientist Juan Linz pointed out that “the vast majority of the stable democracies in the world today are parliamentary regimes” and that, in contrast, “the only presidential democracy with a long history of constitutional continuity is the United States.” Based in part on this observation, Linz concluded that parliamentary democracies are more conducive to stable democracies that presidential democracies.

Linz thought the United States was the exception. What, according to Linz, made the United States exceptional? His answer was that it lacked political polarization and instead had a large moderate consensus that avoided catering to extremists. But this is no longer true.

The Truth-Revealing Power of Courts

Lots of people in the United States (and elsewhere) are pessimistic about their ability to distinguish the truth from falsehoods. This is perhaps unsurprising given the relentless attack on truth that the United States experienced during the previous presidential administration.

As one observer recently put it: “There’s so much information that’s biased, that no one believes anything. There is so much out there and you don’t know what to believe, so it’s like there is nothing.”

Given all the uncertainty, polarization, and misinformation people have experience worldwide recently, this is an understandable reaction. Still, it’s troubling. It is hard for individuals or societies to function well without reliable access to truth.

No single solution will fix all of such epistemic challenges. Still, I think we can make meaningful progress by broadening our focus beyond just who or what to believe, to consider when we should believe.

Sometimes answering the question “When should I believe someone?” is enough to help dispel a fog of confusion. The reason why is rooted in common sense: people are more likely to be honest under some circumstances as opposed to others.

Propagandists, Degrees of Reliability, and Epistemic Nihilism

Reliability is a quality that comes in degrees. For example, a bus that always arrives exactly on time is highly reliable. A bus that often but not always arrives on time is somewhat reliable. A bus that rarely arrives on time is unreliable. People living in areas with public transit commonly discuss which among the less-than-perfectly-reliable modes of transport available are more or less reliable. In doing so, these people show they understand that reliability comes in degrees. They readily acknowledge that some imperfect modes of transport are more reliable than others.

Propagandists prefer their audiences ignore this level of nuance when assessing sources of information. A propagandist prefers that you perceive the propagandist as totally reliable while perceiving all other sources of information as totally unreliable. If this cannot be achieved, the propagandist would prefer that you view all sources as completely unreliable. At least then your decisions about whose claims to trust will rest on grounds other than the reliability of the source.
